CiteStamped reference-health badge
20/20 checkable references clean · checked 2026-10-19

Every reference with a DOI or an arXiv id in the deposited reference list resolved to a known work in Crossref or DataCite at the dated check, and none carried a retraction, withdrawal, or removal notice.

5 with no DOI or arXiv id: not checked. A reference deposited without a DOI is checked only when it names an arXiv id, under that id’s DataCite DOI. The rest are never matched by title or guessed at; they stay outside the checked set, and this line says so.

What this badge says. CiteStamped means the CHECKABLE references of this work were clean at the dated check: each resolved to a known work in a public registry, and none carried a retraction notice at that time. If Crossref’s record marks the work itself retracted, withdrawn, or removed, the badge says so instead of showing clean. It says nothing about the quality, findings, or importance of the work itself, and nothing about references with neither a DOI nor an arXiv id.

checked 2026-10-19 — re-checked at most once a day, when someone opens this page, so the date shown is the last check; titles and statuses come from Crossref and DataCite and are not part of the signed record
